It does make me a little sad that the DT bindings need to specify the number of steps but otherwise this looks good (modulo the minor comments Stephen had as well): Reviewed-by: Mark Brown <broonie@xxxxxxxxxxxxxxxxxxxxxxxxxxx> I think regardless of the current discussion about some of the applications (like pwm-backlight) there are going to be cases where this is useful even if it ends up being more as library code for drivers than as something that users work with directly. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
